HYDROCARBON-BU RN ER.

SPECIFICATION forming part of Letters Patent No. 417,457, dated December1'7, 1889 Application tiled February 29, 1888. Serial No. 265,655. (Nomodel.) Y

To all whom' it may concern:

Be it known that I, WILLIAM WILSON, a citizen ofthe United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Hydrocarbon-B urners andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart towhich it -appertains to make and use the My invention is animproved lburner for hydrocarbon'oils.

The object of the invention is to provide a burner of simple andeconomical construction and adapt it to vaporize effectually hydrocarbonoils of any density. It is included in that class of burners in whichthe oil is vaporized by the heat of its own combustion; and theinvention consists in the special construction, as hereinafter fullyexplained, and illustrated in the accompanying drawings, in which-Figure l is a vertical central section through the generatorl andburner. Fig. 2 is a perspective View of a part of the burner.

In the drawings the vaporizing-chamber A is represented of tubular formand may be made of a piece of iron pipe or cast with one end integralwith the body. A cap a in the form shown is screwed onto and covers theupper end. A pipe B, formed on or inserted through the lower headb,`extends axially to near the upper end of the chamber. The upper endof the pipe is closed; but lateral openings c are provided in the pipeand near its end, just above an annular flange (l, which extends fromthe pipe horizontally into the chamber. This pipe Bis connected to anySuitable pipe D extending from a tank for the supply of the hydrocarbonto the chamber. Around the lower end of the vaporizingchamber is xed anannular upwardly-curved flange E, which forms with the wall of thechamber A an annular' trough or cup about the bottom of said chamber.

Within the oil-pipe B is a pipe H, which passes through the end of pipeB and opens into the chamber. The pipe H is smaller in external diameterthan the interior diameter of the oil-pipe, so that an annular space isleft for the flow of the oil. The pipe I-I leads to any suitable water,steam, air, or gas supply, and it and thepipe Behave suitable cocks forthe regulation thesupply of oil or water.

Within the chamber Ais placed a filling 'of pipes M, leading from thebottom of the generator.

They are turned outward and upward and have suitable tips m. These tipsare arranged in a circle about the generator. Over themis located theburner. It is mainly composed of two annular plates O P, one above theother, suitably supported in proper relation to each other and to thegenerator, substantially as shown. Over each ti-p is an opening in thelower plate, in which is placed a tube q, the lower end of which extendsto the tips of the vapoiaducts and the' upper end into the space betweenthe plates, but terminates a little below the upper plate, leaving aspace for the flame or vapor to pass over the upper end of the tube. Onthe under surface of the upper plate P is a flange a', surrounding theupper end of the tube, caus-v ing a more perfect mixture of the vaporand air, and thereby more complete combustion.-

The plates are connected to form an annular combustion-chamber by meansof perforated walls fr, and the said chamber surrounds the centralchamber A. The tube q, the flange, and the walls may be circular, asshown in Fig. 3, or the tube and 'llange may be elongated or ot' ovalshape. In either shape or of any cross-section the tube serves to drawin the air necessary for the complete combustion of the vapor. The sameeect may be produced by having two concentric burners; but either willbe sufficient when the generator is working to its fullest capacity. Theupper plate becomes heated andin turn aids in the combustion of thevapor, which, rising through the tube, impinges against it.

ame from the circle of burners around the generator supplies heatthereto sufficient to produce constantly the required amount of va- IOOThe

por. The annular ou p about the base of the generator serves in the formjust described to hold an amount of the hydrocarbon to start theapparatus.

The annular combusiion-chamber, as shown in Fig. 1, is supported fromthe outer rim of the trough E by mea-ns of lugs v1, having dependingfingers fitting the rim of the said trough, as shown. At suitableintervals openings are made through the upper and lower plates of thecombustion-chamber by means of the pipes s, and through these pipes airmay pass for aiding in the combustion, the air in this manner beingdirected between the inner and outer flames.

I do not limit myself to the use of steam produced in the generator. Itmay be generated elsewhere and forced through the inner pipe, or undersome circumstances air may be used. This may be desirable in connectionwith some oils. A very small amount of air, gas, or steam, or a mixtureof any of these, will produce, even from heavy oils, a very superiorheating-vapor.

I claim as my inventiony l. In combination with the chamber A and itsfilling, a central oil-supply pipe B, burners leading from the chamberA, and a combustion-chamber consisting of the annular plates O P, havingperforated sidewalls and openings in the bottom plate to the interior ofthe combustion-chamber, said openings being in line with the burnersleading from the chamber A, substantially as described.

2. In combination with the chamberA and its filling, a central oil-pipeB, burners leading from the chamber A, a combustion-chamber consistingof the annular plates O P, having perforated side walls, tubularopenings in the bottom plate in line with the tips of the burner, andtubular openings through both upper and lower plates for the passage ofair, substantially as described.

3. In combination with the chamber A and its filling, the centraloil-supply pipe B, burners leading from the chamber A, acombustion-chamber consisting of the annular plates O l), connected byperforated side walls, tubes exten ding through the chamber formed bythe plates, tubes q, extending through the lower plate covering the tipsof the burners, and a liange a', formed on the under face of the upperplate, substantially as described.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
